flexrac Posted March 3, 2018 Share Posted March 3, 2018 I'm trying to find the setup.bin but could not find it, tried searching for 899407d7 xxxxxxxxx per jakes suggestion in other posts but search came up empty. System specs Dell optiplex 3050 Core I3 7100 (7th gen)/3.9 ghz dual core Intel 250 express Intel HD graphics 630 4gb DDR4 2400 mhz 500gb HD Sata Realtek Ethernet Realtek HD audio/Intel display audio Bios attached if anyone care to look.

Moderators Jake Lo Posted March 3, 2018 Moderators Share Posted March 3, 2018 If you don't want to mod the BIOS as it might be difficult for some models, you could skip this step by adding 2 new kexts to /EFI/Clover/kexts/Other Lilu.kext & IntelGraphicsDVMTFixup.kext Note: While searching for the GUID 899407d7-99fe-43d8-9a21-79ec328cac21 I was able to find and extract the body of PE32 Image section Converted it to text file Able to search the text file for DVMT 0x795 and 0x796 Link to comment Share on other sites More sharing options...

I guess once the patch is applied I have to remove dvmtfixup.kext and restart and see if that works. So I have to run code for EFI shell as per below setup_var 0x795 0x3 or setup_var 0x795 0x2 (as I dont have 96M) Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted March 23, 2018 Moderators Share Posted March 23, 2018 Hmm, give it a try with setup_var 0x795 0x3 There's another alternative, add to kernel and KextPatches the following (use Clover Configurator): Name*= com.apple.driver.AppleIntelKBLGraphicsFramebuffer Find* = 00006002 00005001 Replace* = 00003001 00009000 Comment* = 0x591b0000, 32MB BIOS, 19MB framebuffer 9MB cursor bytes (credit RehabMan) Link to comment Share on other sites More sharing options...
shania Posted March 23, 2018 Share Posted March 23, 2018 THanks. Ok will give a shot in 30 mins when I home. But bare in mind that I have intel HD 530 and patch above refers to 0x591b0000 which is intel HD 620. Also after applying this patch should I remove dvmtfixup.kext?
